Its a good thought to provide all indians with free internet, but while providing it free most people provide it for granted like no proper care is taken about customer feedback or so, because as it is for free people tend to ignore the difficulties they are facing and use it for someother purpose because its free and it should be utilised rather than complaining for the things that are not working. So anyway its good, but it has some calling and connectivity issues sometimes, and the internet speed has gone drastically down from the starting month and the jio apps are a must if u are using this sim, so its kind of a drawback. But since it has created awareness about going digital and upgrading the technology of india it is good.
You should once use the benefits of this jio sim for sure.
